Stretch bei Panel?

[ReDoX]

Ich benutze die funktion

Delphi-Quellcode:

const
  WM_CAP_DRIVER_CONNECT = WM_USER + 10;
  WM_CAP_EDIT_COPY = WM_USER + 30;
  WM_CAP_SET_PREVIEW = WM_USER + 50;
  WM_CAP_SET_OVERLAY = WM_USER + 51;
  WM_CAP_SET_PREVIEWRATE = WM_USER + 52;

function capCreateCaptureWindow(lpszWindowName: LPCSTR;
  dwStyle: DWORD;
  x, y,
  nWidth,
  nHeight: integer;
  hwndParent: HWND;
  nID: integer): HWND; stdcall;
  external 'AVICAP32.DLL' name 'capCreateCaptureWindowA';

procedure GetPic(Panel: TPanel);
begin
  Picture := capCreateCaptureWindow('Video',ws_child+ws_visible, 0,
  0, 640, 480, Panel.Handle, 1);
  SendMessage(Picture, WM_CAP_DRIVER_CONNECT, 0, 0);
  SendMessage(Picture, WM_CAP_SET_PREVIEWRATE, 30, 0);
  sendMessage(Picture, WM_CAP_SET_OVERLAY, 1, 0);
  SendMessage(Picture, wm_cap_set_preview, 1, 0);
end;

Und da muss ich

Picture := capCreateCaptureWindow('Video',ws_child+ws_visible , 0,
0, 640, 480, Panel.Handle, 1);

das handle angeben.

Edit: @ helmi Ich möchte ja das panel klein halten also nur 320x240 und da soll alles drauf zu sehen sein.
